ABSTRACT:
An AC-DC converter includes a rectifier DB for rectifying an alternating current supplied from an alternating power source AC, a power factor controller11aconnected to an output side of the rectifier DB to improve a power factor and also output either a power or a current limited to a predetermined value, a DC-DC converter12that converts a voltage outputted from the power factor controller11to another voltage, a capacitor EDLC for storing an energy and a two-way converter13having one input/output terminals connected to the output side of the power factor controller11aand the other input/output terminals connected to the capacitor to carry out a two-way power conversion.
